The invention concerns a process for converting a stream of natural or associated gas into liquid fractions, comprising:

Process for converting gas into liquids with simplified logistics

Process for catalyst preparation

Process for the preparation of a catalyst based on cobalt and scandium

Catalytic composition suitable for the fischer-tropsch process

A process for the synthesis of essentially linear saturated C.sub.5.sup.+ hydrocarbons from a gas phase comprising synthesis gas is described. The process comprises circulation of an inert liquid phase and said gas phase in a reaction zone, in which the reaction zone is provided with at least one means for introducing gas and liquid phases, and at least one means for extracting the hydrocarbon phase formed by the Fischer-Tropsch reaction, and characterized in that the reaction zone comprises at least one mixing means. Preferably, at least one mixing means is a static mixer. An apparatus for carrying out the described process is also described.

Conversion of synthesis gas to hydrocarbons in the presence of a liquid

In the synthesis of essentially linear saturated C.sub.5.sup.+ hydrocarbons from synthesis gas, the reactive gas phase circulating either as a downflow or as an upflow through a fixed bed catalytic reaction zone, an upflow of an inert liquid phase through said zone at a superficial flow rate of more than 0.01 cm/s, as compared to a downflow of liquid phase, increases the selectivity of the process to the formation of the desired C.sub.5.sup.+ cut.

The invention concerns steps in a process for the synthesis of at least one alkyl tertiobutyl ether, preferably respectively MTBE or ETBE, from at least one alcohol and from isobutene, each synthesized at least partially from natural gas. The alcohol, preferably methanol or ethanol respectively, is synthesized at least partially from synthesis gas, a portion of said synthesis gas being prepared in a natural gas steam prereforming zone. The isobutene is synthesized in a series of processes which includes direct transformation of natural gas to ethylene, known as oxidative coupling of methane (OCM), dimerisation of ethylene to normal butene, isomerisation of n-butene to isobutene, and the separation units associated therewith.
